What to expect

MP3is silent, a different track may have been selected by default. - All video, subtitles, and chapter markers are discarded; the output file contains audio only.
Frequently asked questions
Can I extract MKV audio without losing quality?
Only if the audio track inside the MKV is already MP3. For any other codec, re-encoding is required and some quality is lost.
Why does VLC take so long to convert?
VLC processes the file at 1x playback speed, so a 90-minute film takes 90 minutes. FFmpeg typically runs 10-50x faster.
The output MP3 has no sound - what went wrong?
The MKV likely contains multiple audio tracks and the wrong one was selected. Run
ffmpeg -i input.mkv to list all available tracks.Can I convert just part of an MKV to MP3?
Yes - with FFmpeg, add
